Abstract
The magnetization reversal process and thermal stability of perpendicular coupled film glass/Ti 40 nm/CoCrPtB 35 nm/CoDy 20 nm/Ti 4 nm were analyzed. It was shown that the exchange coupling constant with Dy content near the compensated point is as high as 1.3 erg/cm 2. The dependence of exchange coupling strength on the Dy content and the thickness of CoDy layer was described. It was found that the thermal stability of the coupled films show an increase over 100%.
